Some of that is almost too pretty.
I find the Thiesen Automobile Raritäten mailing list does similar. It started years ago when I contacted them about a car I'd seen on their site and thought it might be something to aim for in the future. They responded very promptly and politely, noting the seven digit price...
I've been on their mailing list ever since and it's most enjoyable to see what utter beauties they have.
